Abstract

This articledealswith auniquemass-occurrenceofMyrica fromPitsidia (southernCrete,Tortonian).Foliage, fruits and infructescences as well as male catkins are preserved as imprints, sometimes coated by an iron-rich encrustation exhibiting systematically relevant morphological details. Leaves are assigned to Myrica lignitum (Unger) Saporta, fruits sometimes even attached to their infructescence axis to M. ceriferiformis Kownas, and male catkins to M. cf. goeppertii Kohlman-Adamska, ZiembińskaTworzydło & Zastawniak. The taphonomic evidence indicates that the different plant organs derive from a single species of Myrica. The fruit size, the unbranched male catkins and mainly the fused filaments into a staminal column in the male flower, clearly pointing towards the section Cerophora (sensu Chevalier 1901) of the subgenus Morella. This points to a closer affinity to the American, African and Macaronesian species ofMyrica than to Asian ones.Myrica cerifera L. is supported as the most similar living relative in terms of gland density on the leaf surface, fruit morphology and male catkin form. The infructescence axes bearing M. ceriferiformis fruits are, however, longer with a higher number of fruits than inM. cerifera. Contrary toM. cerifera, inM. cf. goeppertii the catkins are somewhat longer and the staminal column is shorter than its floret bract.Myricawas probably a dominant taxon along withPinus in an early successional stage of near-coastal wetland forests in the surroundings of Pitsidia. In southeasternNorthAmerica, modern early successional Pinus palustris forests withMyrica cerifera as a differential species serve for comparison.
Pitsidia(克里特岛,中新世晚期)植物组合中的杨梅:将谜团拼凑在一起
这篇文章讨论了来自mpitsidia(克里特岛南部,托尔顿)的杨梅的一次独特的大规模发现。叶子、果实和果序以及雄絮被作为印记保存下来,有时被富含铁的外壳覆盖,显示出系统相关的形态细节。叶片被分配给杨梅(Myrica lignitum (Unger) Saporta),果实有时甚至附着在M. ceriferiformis Kownas的花序轴上,雄柳被分配给M. cf.goeppertii Kohlman-Adamska, ZiembińskaTworzydło & Zastawniak。地语学证据表明,不同的植物器官来自同一种杨梅。从果实大小、雄花不分枝的雄花絮和雄花中主要融合成雄蕊柱的花丝来看,可以清楚地指向山茅亚属(senu Chevalier 1901)的Cerophora剖面。这表明与亚洲的杨梅品种相比,它与美洲、非洲和马卡罗尼亚的杨梅品种更接近。杨梅在叶面腺体密度、果实形态和雄柳絮形态方面被认为是最相似的现存亲缘植物。然而,果序轴长,果数多于果数。cerifera。相反,汤姆。cerifera,立即通知。花絮稍长,雄蕊柱短于小花苞片。在Pitsidia附近近岸湿地森林演替的早期阶段,杨梅可能与松属一起是优势分类群。在北美东南部,现代早期演替古松林与杨梅作为区别种可供比较。

期刊介绍: Section B of Palaeontographica publishes contributions to palaeobotany, i.e. papers on morphological traits, systematics and phylogenetic features of plants as well as papers on palaeoclimatology and palynogeography. Especially worth mentioning are the comprehensive monographs published in Palaeontographica B on specific floras or plant groups. Often palaeoclimatic or stratigraphic problems are clarified by resorting to palaeobotanical data published in Section B of Palaeontographica. Throughout the last decades, numerous objects important to palaeophytology have been found in many places all over the world. As Palaeontographica publishes papers on floras on any parts of the world to report world-wide research, contributions in German, English and French have been published since the beginning of the journal, today English language publications are preferred. Palaeontographica B is of interest to palaeobotanists, palynologists, palaeoclimatologists, stratigraphers and the libraries of all institutions engaging in such research.
